摘要
目的探讨应用视神经管减压术治疗急性外伤性视神经损伤的临床疗效。方法回顾性分析2002年1月至2008年1月行显微镜下视神经管减压术治疗的12例急性外伤性视神经损伤患者的临床资料。结果4例无光感患者中,2例改善,2例无改善;6例眼前光感患者中1例无改善,2例恢复至眼前手动,2例恢复至眼前1米内数指,1例恢复至术前正常视力;2例眼前手动患者基本恢复至术前正常视力。除去1例非手术所能解决的视神经横断患者,11例中无改善2例(占18.18%),有效3例(占27.27%),显效5例(占45.45%),特效1例(占9.10%),总有效率81.82%。结论视神经减压术的效果取决于视神经受损程度及手术时机的把握,减压有效的时间在伤后5天以内,手术越早,效果越好。
Objective To evaluate therapeutic effects of optic canal decompression in treatment of acute traumatic optic nerve injury. Methods Twelve operated patients with acute traumatic optic nerve injury were reviewed retrospectively from Jan, 2002 to Jan ,2008. Microsurgical optic canal decompression was carried out in all cases. Results In 4 patients with no light perception ,2 patients,eyesight improved and another 2 was not; In 6 patients with light perception in front of the eye, 1 patient didn, t improved, 2 patients recovered to see hands waving in front of the eye ,2 patients recovered to calculate fingers within 1 m in front of the eye, 1 patient recovered to preoperative normal eyesight ; 2 patients who could see hands waving in front of the eye recover to preoperative normal eyesight, with the exception of one case whose optic nerve was nearly intersected,in other 11 cases 2 cases didn, t improved （ 18. 18% ） , 3 cases were effective （ 27. 27% ） , 5 cases were significant effective （ 45.45% ） , 1 case was predominant effective（ 9. 10% ） , the total effective rate was 81.82.%. Conclusions Efficacy of optic canal decompression depends on the degree of optic nerve injuries and delay of operation from the injury. Well-recovered patients were those operated within 5 days, the earlier time and quicker recovery.
